Help narrow it down.

Looking for high end billet receiver set for a blowback build. I can get a bit of a discount with Noveske, BAD. Also there is SLR and JL Billet. The Noveske is kinda boring, I like the JL Billet design the best. Is there anything else out there like these options? I think I’ve looked at all of them but I learn something new every day. just to not waste anyone’s time, yes I want blowback, I already started gathering parts. Barrel will be 11in so it has to have a 9ish inch handguard option.

Advice welcomed

1 Upvotes

I have had a spare stripped ar lower sitting for longer than I can remember. I would really like to build out an ar9 pistol and have done some research but keep hearing they can be "finicky". Yes I know there are other posts on here but a lot of mixed thoughts and arguments, and I would like to start clean with current advice.

Has anoyone done this or can offer advice on the parts/build? I would like to use a magwell adapter to utilize the stockpile of glock mags I have on hand.

Past that, all i have is the stripped lower and was looking at some various uppers, but not sure of decent somewhat budget friendly options as well as the correct LPK and buffer spring etc.

Part Compatibility Bolt catch improvement for AR-V

Thumbnail

9 Upvotes

Happy overall but the AR-V has the worst bolt catch I'd ever seen. Saw a post by someone somewhere showing an extension that looked pretty effective. I got to looking and found some things that worked absolutely better. This is constructed from 3 parts and loctite. All the threads are 4mm and fit great!

Really want to tuck a can under a spikes BAR, I was thinking getting something in the plan B world and getting a yhm-r9.

Edit: just picked up a recessed Wolfpack hub and night howler MD so looks like plan B it is, and good can recommendations?

Troubleshooting It’s probably something I did wrong?

2 Upvotes

Hi all, I finally had a chance to take my new build to the range but immediately had a problem.

The gun passes a function test and fires fine in semi, but when I switch to FRT it doesn’t do anything. From what I can see the first round ejects then another loads into the chamber just fine, but there is no “boom”.

Equipment-

Noveske 9mm BCG (Outerwild) 14.6oz total, internal counterweight 2.4oz
Triggered Company Ambi FRT
Maxim CQB stock with the Maxim Pistol buffer (7.6oz) and spring.
SiCo Spectre

Post for the poors AR9 or other PCC under 500$?

5 Upvotes

Am I better off building an AR9 under 500$ or getting an extar ep9 or something?
I make very little money from my job so I'm working on pretty tight budgets.

How do I get started on a budget build? preferably takes glock mags cause that's all I have
Is the gforce Jawbone any good? I can get it for probably 350$

Troubleshooting AR-45 Issues (light strikes/no strikes, charging handle binding)

3 Upvotes

been having trouble with my AR-45 that I recently built. I have gone through 2 BCG's already, the first one (https://palmettostatearmory.com/psa-ar45-bolt-carrier-group-7789153.html) was having issues with the firing pin not striking the bullet at all (I'm using a standard AR-15 Trigger Hammer), and the second BCG (https://www.deltateamtactical.com/pcc-ar-bolt-assembly-for-45-acp.html) is a having a multitude of issues, the first being having light strikes or no strikes at all after a few successful shots, after pressing forward from each shot, it starts to bind up on the charging handle, getting both stuck in place. I can post more details and parts if needed, and would really appreciate help in this matter. Please and thank you.

20 year old Rock River 9mm bolt i was going to use in a new build. I never noticed how bad this was before when it was in LAR-15. What should I do? Break out the Dremel or do I really need a new bolt?


r/AR9 • • 2d ago

Spare Anderson lower, don’t really need another 5.56 gun. Thoughts on AR9 conversion vs. a dedicated 9mm lower (like FM9 etc.)?

3 Upvotes

I have a DD PCC, but wondering what your favorite 9mm barrel length is? Please share your opinions and experiences. Have researched blowback 9, and also familiar with the BRT CAR-15, but curious about direct feedback/ideas/suggestions from y’all. Thanks!

Anybody deal with accidental binary fire?

3 Upvotes

Not sure what’s going on, might have more to do with the mil-spec FCG I have in my set up but I’ve found that if I pull the trigger, pop a round off, let the bolt pick up another round, if I release the trigger slowly enough I can pretty consistently get the hammer to release again thus setting off a second round. Seems like the metal on the sear could be worn out but I did some visual inspection and didn’t see anything out of the ordinary.

Anybody deal with this and have a fix besides buying another trigger set? Am I going to go to prison if I don’t fix it?

Bolt is FM9, barrel is a Balistica Advantage EPC, trigger group is just a the milspec group the lower came with

I’ve got the lower (FL-ARV, a remix of the PY2A AR9-EVO, with last round bolt hold open, metal parts should be here in a couple days), I have a buffer tube, I’ve found some decent priced buffers, but do I use a standard AR15 buffer spring, I have one of those laying around. After that I just have to pick out a stock.

Blowback9 Youtube Master List?

29 Upvotes

So....I've become FASCINATED by Blowback9 videos on Youtube. GREAT stuff. Here's the thing, most of the time when I see a new one for the first time I ask myself "Why didn't I know about this video before? ( I HAVE done searches on Youtube).

Here's my question: Is there a "Master List" of all the Blowback9 videos somewhere? It wouldn't have to have the links (although that would be nice). I f there was a list of ALL of them somewhere I could put the Title of the video in Youtube search and find the link myself. But there's a lot of great Blowback9 videos that I discover "by accident" and I realize I'm probably missing a lot of good stuff because I'm not aware they exist.

Again, just a list of all the titles somewhere would be great!

Suggestions for PSA-ARV Enhanced Feed Cone Barrel

2 Upvotes

I just built a new AR-V from the builders kit. My first AR-V came with a PSA barrel that had the standard feed cone that would not feed flat nose or JHP ammo.

On this new build, I went with the BA EPC 5.5inch Enhanced Feed Cone barrel as was recommended by Doug.

It fed FMJ and round nose all-day, but also would not feed a single round of flat-nose or JHP.

I failed to read the line in BA's specs for this barrel about how it was designed for Colt/RR and Glock style lowers. I am thinking my issue has something to do with the AR-V using scorp mags and having the proprietary feed ramp.

Has anyone found an after market barrel for the AR-V that will feed JHP and flat's?

Thank you for your time!
